TYPE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 526,822, dated October2, 1894. Application filed May 9. 1893. $erial No. 473,561. (No modeldTo all whom it may concern:

Be it known that I, ROBERT A. STEWART, a citizen of the United States ofAmerica, residing at New Rochelle, in the county of Westchester andState of New York, have invented certain new and useful Improvements inType-Holders, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This improvementis designed to provide a type-holder intended mainly toreceive rubber type but which may be used for type of other materials ifdesired.

The invention will be more fully hereinafter described and thendefinitely claimed at the end hereof.

In the accompanying drawings-Figure 1 is a perspective view on anenlarged scale of a hand stamp provided with myimprovement. Fig. 2 is asimilar view of one of my springplates or partition strips detached.Fig. 3 is an end view of a modification.

Referring now to the details of the drawings by letter, A represents theheador support to which is secured a handle B. In the head A are slots 0G into each of which are placed two independent plates or partitionstrips D D of spring metal similar to that shown in Fig. 2, and having ashoulder 0?, thus forming parallel grooves E E for holding the type. Thepartition strips D D are formed in the shape shown so that they may wheninserted in the head A, make the grooves E larger at the bottom thannear the top to permit type to stand level on their base while beingfirmly held in place by the spring formed by the shoulder at of thepartition strip D.

I propose to make the slots 0 O of a size to conform closely to thethickness of the partition strips D D so that when the partition stripsare forced into place, they will not be easily moved out of position,but to prevent any trouble that may possibly be caused by expansion orcontraction of the head A under atmospheric changes, I make holes (1' ineach, and insert stay rods or pins E through them and the head A, asshown in Fig. 1. Besides this, these rods or pins act to strengthen theblocks and keep them from splitting where they are weakened by makingthe saw cuts to receive the plates.

Although I prefer and use the form of partition strip shown in Figs. 1and 2, I do not desire to limit myself thereto, as different forms ofpartition strips may be used without departing from the spirit of myinvention. They maybe made to overlap as shown atD' in Fig. 3, butpreferably without touching at the top. a

Although I have shown and intend to use my type-holder mainly in handstamps such as shown in the drawings, yet I do not limit myself to thisuse, as my invention may be used in other forms of printing mechanisms.Instead of making the head in one piece and making slots in the same,the head may have its back in one or more pieces, and strips may beplaced between the partition strips, the strips and partition stripsbeing then secured to the head.

I am aware that type-holders have been made with folded metal partitionsor strips and with solid wire partition strips as well as woodpartitions, but these differ essentially from my invention, for from theabove description it will be seen that I have produced a head with typegrooves formed by partition strips of such shape that while they makegrooves much larger below than above, they also form springs to hold thetype in position while in the grooves.

By using independent plates inserted in contact with each other in thewood, the lines of type may be set closer together, as there need beonly the thickness of two plates between two lines, or where the topsare formed as in those in the center and right hand side of Fig. 3, onlyone thickness of metal is necessary between the lines, while in stampshav' ing folded plates of metal with a space between for the receptionof the fastening devices, the lines of type are necessarily thethickness of such fastening devices wider apart than in my invention.

In using the word independent I mean to be understood as referring toand claiming plates, such as are clearly shown in Fig. 2,

10 other at the lower part to hold them in place by frictional contact,and the upper part diverging outside the slots and approaching eachother at their extreme upper edges, substantially as describedo 2. Thecombination in a type-holder, of a I 5 head having a series of slotstherein and a series of pairs of partition strips, each pair tightlyfitting ina slot and in contact with each other at the lower part andthe upper part overlapping, substantially as described. 20

In testimony whereof I aflix mysignature in presence of two witnesses.
